MicroRNAs (miRNAs) represent a class of small, non-coding RNA molecules that are fundamental to the intricate mechanisms of gene regulation. Their pervasive influence extends to a wide array of cellular processes, underscoring their biological significance. The aberrant expression or function of miRNAs has been strongly implicated in the pathogenesis of numerous diseases, positioning them as highly promising candidates for both diagnostic and prognostic applications. Advancements in bioanalysis techniques have progressively enabled the sensitive and specific detection of miRNAs within diverse biological samples, including but not limited to blood, urine, and tissue specimens. This review aims to illuminate the current landscape of miRNA bioanalysis specifically within the context of disease biomarker discovery. Emphasis will be placed on the evolution of technological platforms, the burgeoning clinical utility of miRNA biomarkers, and the prospective horizons for their application in diagnostics and prognostics across various disease spectra[1].
